llhie mechine comprises, generelly e hnrne traction wheels on opposite sides or? the lirorne motor driven roechsnism con-- neetcd to wheels to drive the eonoe ineluding moons operohle to disconnect either wheel so thet the rnechine will be driven hy the other wheel, end hence turn ohout e verce er pessing through the point where oIll'lW/Cliklfil wheel touches the ground. chine also includes steering means res to octtiete one troction wheel other heieg driven loy the *en, l'lQG'fll'lh-lfllSlliL oil the machine, which lorrn, site construe-- troetion wheels mounted .irrron ori opposite sides ot the trains heinrr iisoolly the end ron d, which eirtends Reine it, end held in thereon.

or the pinions 6 is the motor supported h" the trenie l, and. connectcd to the mec enisni which drives the wheels 2. This mechanism con sists of the shaft 7 having members on op- .posite ends-thereof which are connected to the traction wheels 2, respectively, end means for connecting rind disconnecting sold members and the wheels she rnemhers are here shown as pinions 8 which mesh with internel gears 9 loosely mounted on the spindles 3 and connected to the traction wheels Qt, respectively.

The motor shaft 10 is connected. to the shell; 7 by any snitahlenieons here shown as heveled gears ll rind lit mounted-thereon and meshing with opposite sides'oif it pin on 13 on theinotor shaft 10. The it end l9, are loosely mounted on the sho'lt l and are connected there o h-y clutch niechiini cerried thereby end here shown es lltCillltllllg erms M which cooct with ezwenders 15 end l6 slidrihle on the shaft l and o ierehle loy ii hand lever 18 its here shown, the hand lever act-notes on endwisely movzihle rod carrying the forlrs 9310 which shiit ponders The forks are so spaced airport that one expander is in position to clutch its conipanion gear as ll. to the shoitt when the other expander is in position to permit the other gear as 12 to run loosely on the shalt, it heingnnderstood that the geir ll produces forward speed and the gear 1i reverse.

lhe motion of the gears 9 is transmitted to the traction wheels Q through plonetory gears 21 carried. by the wheels 2 around the ones ot the spindles end meshing with gear rings 22 on the gears 9., end with goers 9J3 loosely iriotnmted ot the enter sides ot the wheels 2, on the spindles El, and nor molly held from movement loy the hond steering mechanism to he described, so thot rotation or either geor 9 lorw'erdly will cruise the pinions ill meshing therewith to move pleinetsirily, end hence the correspond in W wheels E5 to he oetnoted lorwerdly.

lhe pinions ore loosely inonnted open the she-lit 7 end ore provided with clutch loces 93st, 525, on opposite sides thereof which coect with clutch sections filth rotetehle with the shalt end clot tehle with the Slit rneilly clutched to the sections rot the drive 'shol't, end ncline is yorov effecting relative ortitl ehi'lftingsrnover ent the clutch sections.

yiinions ll ore shittehle its here shown the till ll it it ll 8: be disconnected from the sha chine will turn a curve about the point the .held traction wheel engages the ground.

The clutch faces 24 are normally engaged with the clutch sections 26, on the ends of the shaft 7, and each pinion 8 is shiftable to disengage its clutch face 24, from the companion clutch section 26, and engage its clutch face 25 with the companion fixed clutch section 27. The pinions 8 are normally held with their clutch faces 24 interlocked with the clutch sections 26, by springs 28 acting on forks 29 which shift said pinions 8. The forks 29 are here shown as carried by rods 30, movable in. the guides 31 which are formed integral with the clutch sections 27, each section 27 and guide 31 being carried by a bracket, the base 32 of which is bolted to the frame 1.

The pinions 8 are shifted out of operative position alternately against the actions of the springs 28, by right and left foot levers 33, 34, in the form of bell cranks pivoted at their angles and having arms 35 which are connected by means of rods 36 to the forks 29, so that movement of the levers 33, 34, will withdraw the forks 29 and shift the gears 8 inwardly into the position shown at the left of Fig. 4. The foot levers are held in their operative position by means of latches 37 coacting with the arms 35, the latches being spring-pressed, and being connected b'y links 38 to the opposite arms of the lever 39 pivoted between its ends to a bracket 40 mounted on the main shaft 4, the links 38 being connected to the lever 39 by pin-and-slot connections 41 which permit either lever 33, 34, to be operated without transmitting the motion thereof to the other of said levers.

The latches 37 are released by means 00- acting with the lever 39 after the machine has turned a predetermined distance.

Said means is here shown as a trailer 42, having a bracket 43 at its front end, the bracket having bearings 44 mounted upon a vertical spindle 45 carried by the bracket 40, and located substantially centrally thereof, and in a vertical plane containing the axis of the spindles 3. When the machine is turning to the r ght, as shown in Fig. 2, which turning is efi'ected by operating the lever 33 so that the right hand traction wheel 2- is held from movement while the left hand wheel 2 receives all of the driving power, the trailer" trails as indicated in dotted lines; and when the relative position of the frame 1 and the trailer changes to a certain extent, one of the stops 46 carried by one of the bearings 44 of the trailer engages a third arm 47 of the lever 39 and rocks the lever 39 to release the latch holding the lever 33.

In Fig. 4, the lever 34 is shown as operated, and when the mechanism is set in this position, the machine will turn to the left until the trailer occupies such position that the stop 46 will engage the arm 47 after the machine has turned to the left far enough to cause the arm 47 to describe the are 50.

The hand steering mechanism comprises shaft sections 51, 52, arranged in axial alinement, means for turning the sections, and means for transmitting the motion of the shaft sections to the outer gears 23 on the spindles 3.

As here shown, the shaft sections are provided with bevel gears 53, 54, on their 013- posing ends, which mesh with the bevel gear mounted on the steering post 56; and said shaft sections are connected at their outer ends to the gears 23 by means of sprocket chains 57 running over sprocket wheels 58, 59, mounted on each shaft section, and on the hubs of the gears 23, respectively.

Obviously, by turning the steering post, as for instance, to the left, the shaft section 52. will be rotated forwardly causing the gear 23 on the right hand spindle to be rotated forwardly, imparting a rotary motion to the planetary gears 21 in addition to that imparted to them by the gear 22, and at the same time the shaft section 51 will be rotated in a retrograde direction causing its companion gear 23 to be rotated in a retrograde direction, thus retarding the forward rotation of the left hand wheel, in}? hence the machine will be turned to the 60 is an agricultural implement, as a mower, suitably carried on the front of the machine, and the movable knife thereof is actuated from the shaft 7, and for this purpose a driving gear 61 is provided on the shaft 7 which maybe connected to, and dis connected from, the shaft 7 by a manually shiftable clutch section 62, in any suitable manner. The mower may also be raised and lowered by means of levers 63.

In operation the machine is steered across the field by the hand steering mechanism and the machine turned around and positioned to out the next swath by the motor driven steering and driving mechanism.
